lclaim.

The invention relates to heating stoves and is shown as applied to a stove of the so-called air,- ltight heater type.

It is an object of the invention to improve upon a stove of this character in details. It is a further object of the invention to provide in a stove of this type for eiiicient automatic action of the draft opening combined with means to pro- A vide a draft by manual control.

It is a further object of the invention to provide an automatic draft control combined with means toA limit the maximum draft which may be given by the automatic means.

,It is a. further object ofthe invention to provide a thermostatically controlled damper with means to vary the thermostatic limits of the control.

It is a further object of the invention to provide a thermostatically controlled damper wherein the control is removable as a unit with the damper for access to-the interior of the stove. K

It is a further object of the invention to provide an ash guard for the draft opening of a stove.

It is a further object of the invention to provide a tool for removal ofthe draft plate as well as for manipulation of the screws securing the same in place. Y

Further objects of the invention will appear from the following description when read in connection with the accompanying drawings showing an illustrativeembodiment of the invention, and wherein Figure 1 is a plan view; l

Fig.' 2 is a front elevation;

Fig. 3 is a detail vertical section on line 3-2 of Figure l upon an enlarged scale;

Fig. 4 is a detail vertical section on line l-l of Figure 2 upon an enlarged scale;

Fig. 5 is a detail perspective view showing the draftplate in courseof removal from the stove;

Fig. Gis a fronjtz'elevation, and I Fig, 'I Vis an edge view of a. tool for manipulating the stove parts;

Fig. 8 is a rear view of the draft plate removed from the stove, and

Fig. 9 is an inside elevation of the base plate to which, the draft opening frame is secured.

As shown the stove comprises a body I0 desirably formed of sheet metal in accordance with the l usual practice, seated upon a base plate Il supvvportedbyiegslz.

The stove. is shown as'provided with a cover plate I2 formed with the usual fuel opening, not shown, which is covered with a swinging cover Il.

pivoted at i5 in the manner more particularly (ci. izo-ss) -v shown in Figure 3. vAs shown in Figure 3, the

pivot for the cover comprises a conical stud il secured to the top plate I2 of the stove. The cover plate Il is provided with an opening I1 fitting over the stud I6 and secured thereon as by a collar I2 and cotter pin I9.

The draft opening for the stove is .shown as interiorly surrounded by means of a frame plate 2li, shown in rear elevation or inside'viewin Figure 9, which is formed with screw openings 2| for attachment to the body of the stove. 'I'his plate is shown as formed with a marginal flange` 22 about its opening to receive the sheet metal lo or the stove body. To prevent ashes which may accumulate in the bottom oi' the stove from falling into the draft opening there is shown 'a swinging Plate 23 Divoted in loops 2l carried by the frame 2li and hanging downwardly to cover the upper portion of the opening in the frame.

To permit of .the swinging ofthe plate 23 out. of the way when ashes Vare to be removed and to the position shown in dotted lines in Figure 4, a link 2l is shown pivoted at 28 to the plate and operable in a lug 21. When the link 25 is swung to the position shown in dotted lines in Figure 4 a notch 2l will contact with the lug 21 to hold the'same elevated. A second notch 29 is shown to preserve the plate in its lowermost position. l

Exteriorly o! the frame 2l thereis shown a frame 20 having a projecting collar Il formed with bosses 22 at opposite sides to receive thumb screws 82 for securingof the draft plate. The draft plate is shown as formed of a member 3l having an edge surface 2B ground to form a good joint withv the edge surface 2l of the collar 3|.

The plate 84 is shown as formed with two openings Il and 3l. each provided with a bisecting 40 member Il, l0, formed with'openings Il, I2, which are interiorly screw-threaded for reception of screw threaded studs 4I, 44, carried by plates which are adapted to be screwed into tight contact as at Il, Figure' 4, with the face of the.J Plate Il.

The plate may be adjusted to manually'control draft oi the stove in' the conventional manner. 'nie draft opening ll however is shown as provided with a thermostatic control. To this end an inwardly projecting coller Il is shown between these two points. ...To this Lend there-is provided with .tamper um at n mmm betweentheopen positionshowninllgure4and'rj e closed-Position. or any intermediate position pme uesbyemuJams-eemnnemwn inl'lsure supporte upon the. interior or the plate. u there isvshown a spiral thermostat Il supported by a revoluble stud It adiustable b'y a linger Il projecting to the exterior o: the plate Il.
